4 Claims.

My invention relates to a safety catch and I declare the following to bea full, clear, concise and exact description thereof sufficient toenable anyone skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawing in which likereference characters refer to like parts throughout the specification.

The object of the invention relates to a device that is applied tobroaches, fraternity andother similar pins, or necklaces, whereby tolock the pin stem within its post and thereby prevent the accidentaldisplacement of said stem with the consequent loss of the broach orother pin.

Furthermore, the'catch is simple in construction. It is made removable,whereby it can be easily replaced when worn or at the will of the user.

The object will be understood by referring to the drawing in which:

Fig. 1 is a perspective view of the device shown applied to a broach.

Fig. 2 is a detailed view showing a perspective of the locking device.

Fig. 3 is a detailed view showing a perspective of the safety keeper.

Fig. 4 is a detailed view showing a perspective of the post or employedmember.

Fig. 5 is a detailed View showing a perspective of the safety keeperwith the members spread apart to expose the interior.

Referring more particularly to the drawing, the device embodies a post Iwhich is soldered to the broach 2 at 3. Post I is made in the form of ahook having its free end 4 open for the reception of stem 5 of broach 2when the broach is Worn.

There is a rotatable keeper member I2 cooperating with post member I,whereby to effect a lock. Laterally extending annular bosses I3, I3 areformed integral with the inner surface of the rotatablekeeper member I2,whereby to hold said keeper I 2 in rocking relation to the free or upperend 4 of post I. To'this end annular bosses I3, I3 fit into the annularopening 6 of end 4 of post I which forms a bearing for said bosses andholds said keeper I2 in place with relation thereto.

Keeper member I2 is made with two duplicate parts l4 and I5 that arejoined together by a part I6 and then bent to be in parallel relation toeach other, part I6 forming in this latter instance a U shaped member.Parts I4 and I5 are circular and each has a central open aperture I'I-formed therein for the projection of stem 5 therethrough. Part I4 ofkeeper I2 is shorter than part I5. Its free end is bent inward at I8, toengage complementary notches I9 and 20 formed in the free end 4 of postI, whereby to hold keeper I2 in either open or closed position.

The upper edge of joining part I6 is enlarged at 29 to provide a fingercatch to aid in rotating keeper I2. Keeper I2 is mounted upon post I bypressing it into place thereon. Parts I4 and I5 will yield sufficientlyto allow bosses I3, I3 to snap into the bearing part 6a of post I. Itcan be removed likewise by pulling it from its assembled position. 5

In operation the user presses stem 5 through the cloth of his or hercoat or dress and engages the free end 24 of stem 5 into the open freeend 4 of post I. Keeper member I 2 is then rotated from dotted lineposition illustrated in Fig. 1 to full line position, whereupon end I8of its member I4 will engage in notch 20 to hold said keeper I2 inlocked position. End I8 will ride in and out of notches I9 and 20 whensaid member I2 is rocked the proper degree by hand.

It will be observed that keeper I2 can be mount ed to post I after saidpost I has been soldered or otherwise secured to broach 2.

Heretofore, some difficulty has been experi enced in mounting safetycatches where the keeper I2 and post I are joined and then post Isoldered tov broach 2. In this instance, the solder flows down andinterferes with the working of keeper I2, whereas in the presentinvention, post I is mounted to broach 2 I2 mounted on post 2 afterwardsby hand.

Having thus described my invention whatI claim as new and desire tosecure by Letters Patent is as follows: v

1. In a safety catch, a post member having an open aperture therein, arock member mounted on said post member, said rock member formed withduplicate parts having laterally extending shoulders that fit within theopen aperture of said first named member, whereby to form a bearing andmeans for holding said members in given relation to each other.

2. In a safety catch, a post member having an open aperture therein, arock member mounted on said post member, said rock member having partswith open apertures formed therein, lateral- 1y extending lugs formed onsaid r-ock member, whereby to fit within the aperture of said postmember to form a bearing and means for holding said rock member inpredetermined relation with said post member.

3. In a safety catch, a post member mounted on a broach, a rock membermounted on said post member, recesses formed on said post membysoldering and keeper her, and a yielding end on said rock member forengaging the recesses formed on said post member, whereby to hold saidrock member in an open or closed position with relation to said postmember.

4. In a safety catch, a post member having an open'aperture therein, a,rock member formed with duplicate parts and having open apertures insaid duplicate parts being bent to engage said post member, said rockmember being mounted on said post member and a third part joining saidduplicate parts of the rock member to aid in rotating the same withrespect to said post member, whereby to open and close the aperture insaid post member.
